cartesianProduct<T extends readonly readonly unknown[][]>(arrays: T): mapped[]

Parameter	Type	Description
`arrays`	`T`	Two or more arrays to combine.

mapped[] — An array of tuples, each containing one element from each input array.

Returns all ordered pairs from two arrays.

cartesianProduct([1, 2], ['a', 'b'])
// => [[1, 'a'], [1, 'b'], [2, 'a'], [2, 'b']]

Useful for generating all size/color variant combinations.

cartesianProduct(['S', 'M', 'L'], ['red', 'blue'])
// => [['S','red'],['S','blue'],['M','red'],['M','blue'],['L','red'],['L','blue']]

If any input array is empty, the result is an empty array.

cartesianProduct([1, 2], []) // => []
